Great location, relatively accessible by car, which seems rare for Riads in Fes and makes it much easier to find (Fes has many tiny, winding streets with no names, so this is easier to find as it's next to the Place Rcif). Once you've delved into the main medina, if you get lost, there are sometimes signs for the Place Rcif, which helps a lot. I would imagine that finding other Riads in the maze of the medina is a little harder.
The Riad itself is stunning on the inside, our room was nice and big, and the staff was fantastic. Our only complaints were:
1) We were cold in the room. It takes several hours for the heater to heat up the room, and the staff turns it off during the day when you are out exploring. If you do stay here in December or another cold month, I recommend coming back in the afternoon to turn on the heater to warm up the room for when you return. We arrived late the 1st night and were freezing. Other nights were better as we kept the heater on for as long as possible and kept doors/windows shut to keep the heat in.
2) We only had hot water once during our 3-night stay (one morning). We tried another morning and at night, and there was no hot water at all.
3) Finally, we got a hammam/gommage in the Riad, and it was not good at all. The man barely scrubbed our bodies, which is the whole point of booking a hammam. I would say not worth it here.
